METHOD FOR MANUFACTURING COIL

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing a coil allowing miniaturization of a coil end in a stator.SOLUTION: A method for manufacturing a coil includes: a crank forming step of forming a step on each of flat conductors 10; a winding step of winding the flat conductors 10 with the molded steps to mold winding 46 with a pair of inside-slot-disposed parts 48 and coil end planned parts 50 and 52; a convex forming step of forming the coil end planned parts 50 and 52 into a convex shape; an opening forming step of performing forming so that the distance between the pair of inside-slot-disposed parts 48 is gradually increased in a lamination direction of the flat conductors 10; and an arc forming step of forming edges 28 and 30 of the coil end planned part 50 into an arc shape.
